A Study of Japanese Traditional Rice Production Technique in Warm Areas and Its Modern Ecological Value

Japanese traditional rice production technique features “sparse seeding, long cultivation, scattered planting and limited transplanting”, and scientific rice production methods of deep plowing, fertilization, weeding, irrigation and drainage are employed. This technique has reversed the common practice of “dense seeding and planting” in rice paddies and changed the history of growing rice spikes purely out of stems, thus enabling stable and high yields of several tillering grain crops including rice. The technique can provide a useful reference for developing modern rice production in warm areas.
